Popis: The study was carried out to determine the effect of sowing time and irrigation on yield, yield components and Charcoal rot disease (Macrophomina phaseolina) of sesame in Dicle University, Faculty of Agriculture experimental field in 2006 and 2007. The six sesame lines (B–60, C–7, C–36, C–53, Y–7, Y–11) which were collected from Mediterranean and South East Anatolia Regions and three Macrophomina phaseolina isolates were used in the study. The sesame seeds were sown early and late before artificially infected by the pathogen before sowing in 05.05.2006, 22.06.2006 and 22.06.2007. The trials were set up in randomized complete block design with three replications. According to study results, the plant height, number of branch, number of pods, yield, weight of 1000 grain and diseases percentage of sesame lines were found to be different according to sowing time and irrigation conditions. The average yields of lines ranged between 97.86 kg/da and 132.80 kg/da according to growing conditions. The highest yield were obtained from C-36 line, and the lowest from Y-7 line. When all growing factors together evaluated, the highest yield was recorded at early sowing time and irrigated plants (117.25 kg/da). The average Charcoal rot diseases percentage of sesame lines were changed according to sowing time and irrigation conditions. The lowest disease percentage were recorded from B-60 line (40.60%), and the highest from C-36 line (%48.98). When all factors together evaluated, the lowest disease percentage were recorded from irrigated (27.56%) and late sowing time (34.73%), the highest from in dry condition (%57.98%) and early sowing time (50.82%).
